As detailed on the official U.S. Marine Corps website, “The Marine Corps, within the Department of the Navy, is organized as a general purpose ‘force in readiness’ to support national needs. Deploying for combat as combined-arms Marine air-ground task forces (MAGTFs), the Marine Corps provides the National Command Authorities (NCA) with a responsive force that can conduct operations across the spectrum of conflict. Recent events continue to highlight the Navy-Marine Corps team’s key national security role. Seabased, combat ready, forward deployed naval forces have been involved in more than 28 major military operations since 1995.”
The heart of the mission of the U.S. Marine Corps is “As America’s expeditionary force in readiness since 1775, the Marines are forward deployed to win our nation’s battles swiftly and aggressively in times of crisis. We fight on land, sea and air, as well as provide forces and detachments to naval ships and ground operations.”
